I am newbie in ionic2, I have made a list of events with sliding Edit and Delete buttons. I have wanted to view the event details page by tapping on the row and it works fine. But if I tap on the edit button, the edit page appears and immediately replaced by event detail page. My code is following:
<ion-list>
<ion-item-sliding *ngFor="let event of eventList" (click)='goToEventDetail(event.id)'>
<ion-item><p><strong>{{event?.eventName}}</strong><p>
<p>Place: <strong>{{event?.place}}</strong></p>
<p>Date: <strong >{{event?.date}}</strong></p>
</ion-item>
<ion-item-options>
<button ion-button color="primary" (click)="goToEditEventDetail(event.id)"><ion-icon name='clipboard'></ion-icon> Edit</button>
<button ion-button color="danger" (click)="removeEvent(event.id)"><ion-icon name='trash'></ion-icon> Delete</button>
</ion-item-options>
</ion-item-sliding >
I have tried by removing "(click)='goToEventDetail(event.id)" event from "ion-item-sliding", in that case I have got expected result. My finding is, after clicking to edit button it fires "goToEditEventDetail" event and after that it also fires "goToEventDetail". I need to stop firing the second event, is there any solution? Thanks in advance.

I want to add a btn in my navbar.html in django-templates, and every time client clicks it, he navigates to page previous to what he in on, and also "naviaget Forward" if clicked other button.
how can i do it?
You can use JS:
<button onclick="history.back()">Go Back</button>
<button onclick="history.forward()">Go Forward</button>
I am working in angular-9 , there are many things which works on reloading, but not after navigation. eg: there are two components A and B. and another component c have a reveal modal code(in foundation).
c component is to be included in both A and B.from component A through navigation I can move to component B which is a another page.
c.ts:
import { FormControl, Validators, FormBuilder,FormGroup, FormGroupDirective } from '#angular/forms';
loginFormControl:FormGroup;
ngOnInit() {
$('#loginModal').foundation();
this.loginFormControl = this.formBuilder.group({
phone_number: ''
});
}
c.html
<div class="reveal" id="loginModal" data-reveal>
<form class="loginForm" [formGroup]="loginFormControl"
(ngSubmit)="onSubmit()">
<input placeholder="Enter Mobile Number" formControlName="phone_number">
<button type="submit" class="button">LOGIN</button>
</form>
<button class="close-button" data-close aria-label="Close modal" type="button">
<span aria-hidden="true">×</span>
</button>
</div>
If I open the modal 'c' in both of the pages A and B on a click of two buttons on both pages with $('#loginModal').foundation('open'); in A.ts and B.ts files, it results me with some unexpected behavior.
1. the modal is open in both the pages. no issue related to view
2. But events of that modal(click,change) or if I enter phone number, It doesn't accept it from user. Even there no event works in a page until i refresh or reload the page.
3. After refreshing a page it will work on that page (including all
events and inputs), there won't be any issue in that page after reloading. but as i navigate to another component B, then it's(c) events and input won't work until i refresh this page too. this same will happen again with component A.
I haven't reach at any solution of this till now and why is this happening. Please let me know if anyone have solution of my problem. It would be fruitful for me.
Tell me please, how to handle onclick action by ID. For example, i’ve something in hbs template:
<button id="myButton" {{action "myAction"}} >OK</button>
it has CSS:
button {color: "red";}
How to do two things by onclick action:
1. Set property to clicked object (only to clicked), eg to set CSS colour “green”,
2. Get some property of clicked (eg CSS colour), and console log or alert.
Thanks in advance!
You can connect the action to the "onclick" event of the button like this
<button id="myButton" onclick={{action "myAction"}} >OK</button>
And then the first argument of the action will be the click event, from which you can take the target DOM element.

The Problem
I push the Root Page to Page2 that supports a side menu, the issue is that when it opens Page2 it shows the back button and hides the menu button for that I've tried to add hideBackButton to Page2 in order to see the menu button but I both the back button and menu button disappeared!
Here is my current code:
<ion-navbar hideBackButton>
<button menuToggle start>
<ion-icon name="menu"></ion-icon>
</button>
</ion-navbar>
The expected behavior should be:
Should hide the back button, and show the menu button.
Ionic Version:
Ionic2
You can't do that following that way; however what you can do is to do a setRoot instead of pushing from the root to Page2
You can use following instead of your code:
<ion-toolbar hideBackButton>
<button menuToggle start>
<ion-icon name="menu"></ion-icon>
</button>
</ion-toolbar>
If you don't want to allow the "back" action on your Page2, and since you face a problem hiding the button, why not removing your root page from the history stack before accessing your Page2?
In such a case, the "back" action not gonna be allowed and the "back" button not gonna be displayed too.
About how to remove a page from the history stack before pushing another page, you could have a look at:

When I add new list items to an existing dropdown button they do not show up on the front end. The dropdown just continues to show the original list items. All my caching systems are off and I cleared the cache locally, but I'm still getting the same issue. Anyone know what could be causing this?
<div class="sidebar-dropdown">
<button data-dropdown="drop" aria-controls="drop", aria-expanded="false" class="large alert round button dropdown">Select Type</button>
<br>
<ul id="drop" data-dropdown-content class="f-dropdown" role="menu" aria-hidden="false" tabindex="-1">
<li>All-Purpose (USA)</li>
<li>Mobile</li>
<li>E-Commerce</li>
<li>All-Purpose (CAN)</li>
<li>Tablet POS</li>
<li>High Risk</li>
</ul>
</div>
The Foundation-generated dropdown needs to be refreshed when new content is added to it. This can be done by adding this to your javascript, which adds a listener to the dropdown element(s):
$(document).foundation('dropdown', 'reflow');
